Fill flash at F2.8 1/8000th sec !

  1. I just thought I would share a trick with the SB24 flash and any Nikon with combined mechanical and electronic shutter [ D40,50,70 ] .
    I just bought a D70S and have an old SB24 with "A" mode . One way to do it is to slide a pice of paper under the two small pins of the flash so the camera doesn't know there is a flash attached , then you can set it at any speed .
    I opened the base of the flash and cut the green wire .
    It could have useful applications in bright sunlight when using fill flash at wide apertures .
    Just as a test I set up this scenario with a bright patch of "sunlight" behind the models head - no flash [ it would be brighter outside of course ] , taken at F2.8 , 1/2000th .

    Turn on the flash , set to iso 200 , F2.8 . "A" mode

    At 1/8000th I lose a bit of the flash power :smile:
